Mopar Radiators

If you have a 1967 - 1974 Mopar radiator, you might be really confused by the lingo that gets thrown around with Mopar radiators. There are 2 basic radiator sizes used in all 1960s through early 1970s Mopar radiators - a 22" radiator and a 26" radiator. The 22" radiator was primarily used in small block applications however was used in a few big block applications. The 26" radiator was used in high powered small block cars and in most big block cars.

The 22" and 26" refers to the core width, however the 22" core raditor is actually 26" wide overall, making it very confusing. The 26" core width radiator has an overall width of 29". To take the confusion out of it and make sure you get the correct radiator for your car, we recommend checking the diagrams below and seeing our fit guide.

In addition to being two different size radiators, there are also two different version of each size. A 26" big block radiator and a 26" small block radiator. There is also two different versions of the 22" radiator with the hose connections in different locations.

For the 22" radiators, the table will show 237X*. Since many of these cars used different radiators and in the case of engine swaps, the hose connections can be reversed. Our part number 2374S has the upper hose on the drivers side and lower on the passenger side. The 2375S has the upper hose on the passenger side and the lower hose on the drivers side.
